emergency closure.

(b) In time periods of less than seven
(7) days, intermediate Saturdays,
Sundays, Federal legal holidays, and
emergency closures are not counted.

(c) Whenever an action is required
within a prescribed period by a

document served in person or by
expedited service; and

(2) By 11:59 p.m. Eastern Time for a
